JONATHAN ROBERTS, OF RUMNEY DEPOT, NEW HAMPSHIRE.

HUNG-ENGAGING CLIP.

To aZZ whom it may concern Be it known that I, JONATHAN Ronnirrs, acitizen of the United States, residing at Rumney Depot, in the county ofGrafton, State of New Hampshire, have invented certain new and usefulImprovements in Rung- Engaging Clips; and l dohereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the artto which it appertains tomake and use the same.

This invention relates to an improvement in rung engaging clips, and hasfor its principal object the provision of means whereby a bracketplatform may be readlly attached to or detached from a ladder and whenin an attached position will be securely retained against accidentaldisplacement.

A further object of the invention is to provide a device of thecharacter described which will automatically return to a position ofclosure after disengagement.

These and additional objects are accomplished by such means as are shownin their preferred embodiment in the drawings described in thespecification and then more particularly pointed out in the appendedclaim; it being understood that various changes in the form, proportion,size and minor details of construction within the scope of the claim maybe resorted to without departing from the spirit or sacrificing any ofthe advantages of this invention.

In the drawings: Figure 1 is a detail side elevation of the device whenattached to the rung of a ladder in operative position. Fig. 2 is adetail side elevation of the device showing its assembled relation witha platform bracket. Fig. 3 is a front elevation of the device. Fig. 4:is a side elevation taken on the line 33 of Fig. 3.

Referring now to the drawings throughout which like reference numeralsdesignate corresponding parts, 5 designates the stiles and 66 the rungsof an ordinary ladder.

My invention consists in a rung engaging clip adapted to secure abracket to the rung of a ladder. This rung engaging clip includes amember 1 secured at one end to the platform bracket and bent upon itselfat its Specification of Letters Patent.

free end and forming a substantially U- shaped recess adapted to receivethe rung of a ladder. The free end of said member 1 is subsequently bentupon itself forming a U- shaped keeper portion. Coacting with the member1 is the latch member 2. This latch member is rigidly mounted on a bolt3, said bolt being projected through an opening 1 in the member Q.Mounted around the stem of the bolt is a helical spring member 5 the end6 of which is fixedly mounted in a radial recess 7 formed in theoperating handle 8. This operating handle 8 is mounted on the boltadjacent its head and is provided with a recess 9 corresponding to andin alinement with the opening 4: in the mem ber 1. An ordinary nut 10 isprovided at the bolt-end 11 to maintain the various parts in assembledrelation. Mounted on the upper guide of the U-shaped portion of themember 1 is a pivoted clip member 12 secured to the said U-shapedportion by the apertured member 13.

The operation of my device is as follows: When attaching the clips to aladder rung, the operator throws the clip 12 out of en gagement with thelatch member 2 and operates the handle to disengage the latch member 2from the keeper portion of member 1 against the tension of the helicalspring. The ladder rung 66 being disposed in the U'shaped portion ofmember 1, the handle is released and the latch member automaticallyreturns to a position of engagement with the keeper portion of member 1.The clip member 12 is then dropped into operative position therebypreventing any accidental disengagement of the latch mem her with thekeeper member.

What is claimed is:

A rung engaging clip comprising a substantially vertically disposedmember having a rung engaging depression formed therein, the upper endof said member terminating in a U-shaped recess, a clip pivotallyconnected to the member and adjacent the recess, a latch member havingits upper end det-achably engaged in said recess and prevented frombecoming accidentally displaced by said clip, a bolt rotatably supportedby the vertically disposed member and having one end fixed to the lowerend of the latch In testimony whereof, I afiix my signamember, a handlehaving one end fixed to ture, in presence of two witnesses. the otherend of the bolt, and adapted to rotate the bolt to swing the upper endof the JONATHAN ROBERTS 5 latch member from engagement with saidWitnesses:

recess, and means to automatically cause en- FRED ROBERTS,
